However, the Labour Party split at the 1931 general election over fiscal policy; Prime Minister Ramsay MacDonald had left the party to form a National Government with the support of the Conservative Party and some Liberals, and Labour's national share of the vote fell disastrously from 37% to 31%.[1] In most seats, Liberal and Conservative candidates agreed a single candidate to stand against Labour, and as a result Labour retained only 52 of the 287 seats which it had won in 1929. Morgan's Camberwell seat was one of those lost.
